A HARPS-N mass for the elusive Kepler-37d: a case study in disentangling stellar activity and planetary signals
V. M. Rajpaul, L. A. Buchhave, G. Lacedelli +22
To date, only 18 exoplanets with radial velocity (RV) semi-amplitudes m/s have had their masses directly constrained. The biggest obstacle to RV detection of such exoplanets i…
Estimating Magnetic Filling Factors From Simultaneous Spectroscopy and Photometry: Disentangling Spots, Plage, and Network
T. W. Milbourne, D. F. Phillips, N. Langellier +21
State of the art radial velocity (RV) exoplanet searches are limited by the effects of stellar magnetic activity. Magnetically active spots, plage, and network regions each have di…
An unusually low density ultra-short period super-Earth and three mini-Neptunes around the old star TOI-561
G. Lacedelli, L. Malavolta, L. Borsato +38
Based on HARPS-N radial velocities (RVs) and TESS photometry, we present a full characterisation of the planetary system orbiting the late G dwarf TOI-561. After the identification…
Global Analysis of the TRAPPIST Ultra-Cool Dwarf Transit Survey
F. Lienhard, D. Queloz, M. Gillon +10
We conducted a global analysis of the TRAPPIST Ultra-Cool Dwarf Transit Survey - a prototype of the SPECULOOS transit search conducted with the TRAPPIST-South robotic telescope in…
The spectral impact of magnetic activity on disk-integrated HARPS-N solar observations: exploring new activity indicators
A. P. G. Thompson, C. A. Watson, R. D. Haywood +21
Stellar activity is the major roadblock on the path to finding true Earth-analogue planets with the Doppler technique. Thus, identifying new indicators that better trace magnetic a…
Temporal evolution and correlations of optical activity indicators measured in Sun-as-a-star observations
J. Maldonado, D. F. Phillips, X. Dumusque +29
(Abridged) We perform a detailed study of the main optical activity indicators (Ca II H & K, Balmer lines, Na I D D, and He I D) measured for the Sun…
